Patented Aug. 30, 1910.

Application filed February 26, 1908. Serial No. 417,981.

To all whom it may concern:

Be it known that I, OLAF OsTLiN, a citizen of the United States, residing in Maywood, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Double-Seaming Machines, of which the following is a specification.

Uy invention relates to improvements in double seaming machines.

The object of my invention is to provide a double seeming machine of a simple, eflicient and durable constniiction, composed of few parts and capable yof being cheaply manufactured, and in which the seaming rollers may beapositively and accurately actuated and easily-aand quickly adjusted and maintained in adjiistment, so as to produce hermetically tight seams, and in which the lower or reciprocating can holder or chuck may be operated by a foot lever or treadle, and in which the seaming rollers while set in operation by action of the foot lever or treadle may be automatically controlled as to their period of operation on each can independent of the foot lever or treadlc, or of the operators actuation of the same.

My invention consists in the means I employ to practically accomplish this object or result, as herein shown and described and more particularly set forth in the claims.

In the accompanyingl drawing, forming a part of this specilication, li`igure l is a side elevation of a double seaniing` machine einbodying my invention; Fig. 2 a front elevation; F ig. 2l a detail section on line 3 2); of Fig. 1; Fig. l a detail vertical section on line l-LJL of Fig. Fig. a top or plan view; Fig. G a detail section on line G-G ot' Fig. 1; Fig. T a detail section of the. clutch mechanism: Fig. S is. a detail section on line S-S of Fig. lg'Fig. E) is a section on line 9 i) of Fig. 1; Fig. 10 is an enlarged vertical' section on the right angle line 10-1O of Fig. S: Fig. 1l is a detail section on line 11 of Fig. S; Fig. 1Q is a sectional view similar to Fig. 10 illustrating a modi fication; Fig. 13 is a detail elevation looking from the line 13-13 of Fig. 12; Fig. 14 is a side elevation, partly in vertical section, illustrating a modification for operating upon rectangular cans; and Fig. 15 is a horiaantal mtionon line 15x-,1559i Fig. 14, Fig.

The chuck B has a operated or moved up and down as required to chuck or clamp' the can against the opposing stationary or nonrotating chuck or disk I) by means of a foot lever or treadle E pivoted to the, frame at El, and furnished with a spring E2 for returning it to position, 70

and which treadle is connected by a pivotal link E with the arm E4 of a rook shaft E5 which has a forked arm E6 necting` block E7 a'djustably secured to the engaging a conoperating rod B1 of the lower can holder B. V75

F is a continuously rotating seaming head upon which the seaming rollers Gr Ga and their movable holders G1 are mounted and by which the same are carried rapidly around the can. The movable holders G1 of 80 the seamingvrollers are preferably levers, as illustrated in Figs. 1 to 11 and 14 and 15, although reciprocating slides may be employed as the tool holders if preferred, as

illustrated Ain Figs. 12 and 13, or other suit- 85 able tool holding means.

The rotary seaming head F has an integral hub furnished with screw threads for removably attaching itto its hollow rotating shaft or sleeve F1, and said seaming head shaft or sleeve is continuously and rapidly rotated by means of a bevel gear f thereon, which meshes with' a bevel gear f1 on the driving'v shaft K, and is furnished with fast and loose pulleys K1 K2 and is journaled in 95 suitable bearings IG on the frame of the machine.

The upper stationary can holder or chuck D is removably connected by screw lthreads d to a stationary or nonrotating shaft on lstem D1, which extends up through the hollow seaming head shaft F1, and which is held in position by guides or arms A2 A3 i on the frame of the machine, and which is furnished at its 'upper end with an ustin screw ull, having nuts und spring c@ and adjusting screw nuts d* to give acljustable yielding support to the chuck lfm ylhe chuck D is further provided with a removable ring D2 to ht the can heed to con-- veniently adept the machine for operation upon eens of diii'erent sizes,

lfhe seeming roller holders Gl are prefer-- ably oi a lever or rocl shaft form, and .are pivotally connected to the seeming head by the shaft or pivot portion g thereof, end each hdve a lower or seeming roller curry ing arm g1 adapted to swing horizontally under the sea-ming; head and upon which the seeming roller is directly mounted. Each of the seeming roller holders or levers (il is also preferably 'furnished 'with a supplemental erin gf2 to which the roller carrying erin g1 is sdjustebly connected, preferably by means ot adjusting notches g3 g4 on said arms g2 g1 in connection with a set screw g5,

this facilitates adjustment of the niachine 'for operation upon cans of diiierent disincters. llach of the sez-Lining roller levers or rocli shafts glis also furnished With. an upper', horizontally swinging, operating erin g, carrying ball and socket joint nienlber g7 preferably adjustably secured thereto by a screw stern gs and set screw g. The operatinggv arms g6 which actuate the nishing rollers G are preferably also provided with supplemental. members glo, between which and the arni g a rubber or other cushion g is interposed, and to which supplemental arm g1 the movable or yielding arin g is ,secured by a clamp screw g1g. rlhis enables the iinishing roller to have a yielding pres sure against the seam and aids materially in producingr hermetically tight double seams 4The seeming rollers are automatically ac- -tuated as required by means of a continuously rotating and. vertically reciprocating head or sleeve H surrounoline@1 the scanning head sleeve F1 and which rotates at the saine speed therewith, and which is connected with the seaming roller operatingl lever g6 by toggle-acting links 71, which have a ball and socket, or other equivalent or universal joint connection With said operating arm gl. Each of the links le, is preferably Jiurnislied with s ball and socket joint member h1 'for connection With the ball and socket joint member g7 on the seeming roller operating arm g. 'As the rotatingr head or sleeve il.' is rcciproccted up and dovvn it withdraws the seeming rollers from the can or throws them inward against the saine. fhe hall and socket or univeisel joint connection between the toggle linirs and rterins enables the lat ,i horizontsl plone, While the swing in vertical planes 'l' rotates.

The sea-ming` roller operating head or sleeve il reciprocsted up and down es required to operate the seeming rollers by means of a roch shaft H1 having a forked erin ll2 en- Y Y a collar z on the sleeve H, and which rock shaft has an erin l# carrying a roller k3 which engages cani ll/l on the cani shaft ll/l1.

The cam shaft lv is intermittently ro teted as required to cause the seeming rollers to be properly actuated during the cycle or period necessary for performing the seeming operation on each een by nieans of e Worn). gear m loose on the cani shaft and continuously driven by a worm ml on the driving gear shaft l, and Which worin gear m is furnished with e, clutch member m`2 und is adapted to be at intervals clutched to the cain shaft M1 by means of at clutch )iu or member ma on. the clutch sleeve mi, which furnished with an annular groove m5 lo receive a Wedge or clutch disengaging device m 'that operates to retract tue clutch pin or member miz ot the clutch member m2 at each revolution of the grooved clutch sleeve mt which is fast on the com shaft M1. rlhe sliding clutch pin or ineniber ma has a notch m to engage the clutch disengaging device m. rllhe clutch pin or ineniber m has a stein m8 engaged by a spring mi), to hold it in engagement with the clutch member m2. lhe cani shaft Ml is also provided With a stop cani lil, having a notch n engaging e. roller "rtl on the lock arm u of the clutch operating lever N1, which is connected by a linl; N2 with the treadle E through'the rock shaft E arno EA1 und liult E. arm 'n2 iswithdrawn from the stop cani on the shaft M1, to permit it to turn at the beginning of each searning cycle or period of operation, by depressing the foot treadle ill which inoves the clutch lever Nl which rlhe locking moves safety device P on the link p into en- A gugelnent `with the trip lever lt ofthe clutch disengaging device m, The trip lever R is l fi'xrnished with s roller r to support the link j? of the safety trip device.

in the modification illustrated. in Figs, 12 and 13 the seeming roller holders are shown as reciprocating slides l2, huvin` adjustable members 'i3 which directly curry the scaming rollers, said members 13 being adjusted on the slides 12 by an adjusting worin 141C engaging arack or teeth l5 on the slides 12. its in this modification the toggle acting arms or levers 172-18, which connect the tool'holdcr slides with the seeming roller operatingn sleeve or head ll, both swing in vertical planes. rl`he universal joint or ball and socket connection between these toggle links or arms is, ot course, unnecessary und is omitted.
